Analyses Of Pile-Soil-Pile Cap Interaction And Random Probabilities

The behavior of capping beam that joints single rank of piles, which nowadays is widely applied to the construction in china, is complexly influenced by many factors. While conversed continuum beam pattern is primarily adopted in existent design methods to predigest computations, it still lacks of satisfaction as a result that it couldn't reflect on the variance of piles and the infection of soil.Consequently, on the basis of non-Winkler foundation model, a finite-element method that utilizes foundation flexibility matrix into iterative calculation is proposed in this paper originated from the item "The Optimal Design Theory and Research of Pile Capping Beam" sponsored by Natural Science Fund of Hunan Province, which the continuity of soil mass can be accounted for under various boundary conditions, different loadings and irregular beam characters.hi addition, with regard to the computation of the maximum / minimum moment, shear force, settlement and foundation reaction of pile capping beam, the randomness of both pile capacity and foundation modulus are statistically analyzed in virtue of the method ?Monte Carlo. Accordingly, the random probability analysis of the internal force of pile capping beam can be achieved.Corresponding exploited computing procedures are introduced in this paper. Furthermore, significant conclusions that can be applicable in practice are also summarized, after contrasting the datum from engineering instances and laboratory model tests, statistically analyzing the differences between dissimilar distributions of pile rigidity, different variance coefficients and various relativity, and probing into manifold factors determining the internal force distribution of pile capping beam and correlative principles.
